Anyone who used the internet between 1998 and 2008 has the uh-oh notification sound burned into long-term memory — that two-syllable concerned bleat that meant somebody had just messaged you. These 25 ICQ sounds preserve the full audio identity of the original Mirabilis messenger: the iconic uh-oh alert, the standard message ping, the contact-online chime, and the dial-up era ringtone variants that played when a voice call came through.
Documentary editors use the uh-oh as a single-shot time-stamp to drop a viewer into the late 1990s without needing a title card. Nostalgia-content creators on YouTube and TikTok layer the ping under early-internet footage for an instant period feel. Indie game designers borrow the alert tone for retro-styled chat UIs because audiences over thirty react to it before the conscious brain catches up. Free to grab, no signup, no attribution.
